Question:
Which of the following contains a coordinate covalent bond ?
Which of the following contains a coordinate covalent bond ?
Updated On: Jul 7, 2022
- $N_2H^+_5$
- $BaCI_2$
- $HCl$
- $H_2O$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
$N _{2} H _{5}^{+}$is formed from $N _{2} H _{4}$ which has a lone pair of electrons on '$N$' and positive charge on '$H$' takes away its electron and to complete duplet, a co-ordinate bond is present from $N$ to $H$.
$H _{4} N _{2}+ H ^{+} \rightarrow\left[ H _{4} N _{2} \rightarrow H \right]^{+}$

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
